Abstract

A high-performance frequency conversion module (FCM) has been developed for ground-based EQ system applications. The FCM unit is built using integrated finline and hybrid MIC (microwave integrated circuit) techniques to achieve a low-noise high-performance millimeter-wave front-end without the use of a millimeter-wave LNA (low-noise amplifier). The FCM unit channels the 18 to 40 GHz into three bands and downconverts each band to a common 8-18-GHz intermediate frequency. The FCM design includes a novel wideband millimeter-wave limiter and millimeter-wave local oscillator for each of the bands. A noise figure of <13 dB was achieved in all three bands with a 50-dB dynamic range.<>
